TITLE/CONTENT OF MAP: 'NORTH AMERICA, South to Panama.'
The map was published within the 1848 edition of the SDUK atlas, but it shows national borders as they existed between 1836 and 1845, although no date is printed on the map itself. The map shows the Republic of Texas as an independent state as it existed between 1836 and 1845; it shows the US-Mexican border prior to the Mexican-American war of 1846-1848 with the present US state of California being shown as part of Mexico; and it shows the border between the United States and British North America (now Canada) as it was before the Oregon Treaty of 1846. The map also shows what is now the US state of Alaska as "Russian America", as it was prior to the Alaska purchase of 1867. The United States - Mexican border shown on the map follows the 42nd parallel east from the Pacific Ocean to approximately the 110th meridien west, then south to the source of the Arkansas River whose course the border follows until it reaches Texas. The Texas - United States border follows the course of the Arkansas river east to the 100th meridien west, then runs due south to the Red River, then east along the Red River to the 32nd parallel north, then due south to the Sabine River whose course the border follows to the Gulf of Mexico. The Texas - Mexican border follows the Rio Grande del Norte. From the point where the Columbia River meets the 49th parallel, the border between the United States and British North America (now Canada) is shown on the map as following the course of the Course of the Columbia River to the south and west until it reaches the Pacific Ocean. Therefore that part of what is now the US state of Washington to the west of the Columbia River (which includes present-day Seattle-Tacoma) is shown on the map as being part of British North America. The Oregon Treaty of 1846 moved this border to the north, setting the US border with British North America border at the 49th parallel with the exception of Vancouver Island, which was retained in its entirety by the British.
